1 MASSACHUSETTS eAsKET Application filed May 11,

This invention relates tostrip packing for use around refrigeratordoors: and in connection with other doors and wmdows to prevent thepassage of air, molsture and heat.

The principal objects of the invention are to provide a. convenientstrip of packing for these purposes which will remain alive andresilient after long use; to provide a 16 packing of such material thatit will not deteriorate and can be molded by a simple molding operationin a single piece; to provide it with a protecting coating all aroundit; and to provide it in a form which will be convenient to apply torefrigerator doors and the like. f f V a Other objects and advantages ofthe invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which r Fig. 1 isan inside view of a door pro vided with packingof this, type andconstructed in accordance with this invention; Fig. 2 is a sectionalview of the same'on theline 2-2 of Fig.1; and I a Fig. 3 is an enlargedexaggerated crosssectional view of the packing itself.

It is well known that the subject of packing refrigerator doors isamatter, that has involved considerable experiment in the lastfew years,owing to the fact thatsuch packing must be heat insulating in a veryhigh degree and to the presence of moisture. Soft rubber packings havebeen, used and 3 also packings of felt and similar materials, but thesoft rubber, packings have not been 3 sufficiently soft and the feltpackings have had a tendency to mat downand get out of shape easily,whileboth of them have been lacking in' the quality of durability. Thisinvention has been designed to avoid, these difficulties chiefly, i

lVe form the packing rubber and prepare itin a long strip in which thereis a main portion 10 of semicircular or similar shape, and a tongue 11projecting therefrom integrally. In its molding it preferably has askinof rubber extending entirely around its .but is capable of beingemployed as window and door stripping, and in factin many places where amainly of sponge surface. 59 Around the entire body is a layer of rubber1929.

ized fabric i2. This is'a'layer or thin finely woven fabric impregnatedwith rubberorlatex, and it extends all the way around the body of thegasket so astoprotect it from c the entrance of% moisture 'into theinter- .55 stices in the sponge'rubber. Thetongue or projection 11extends out in a radial direction and there is-a fiat surface under thewhole width of the fabric includingthis projection. :The fabric 12 iscemented-to the sponge rubber; j r 7 'When applied to an ice-box door asshown,

the projection 11 is fitted" into a recess or, 'rabbet 14 in the door'15, and the fiat surface of the packing is cementedbya liquid 1 Irubber cement,-or otherwisesecur'ed, to'the projecting surfacelG of thedoor. I

Fig. 2 shows the door closed against the jamb 17 and it will be seenthatithe gasket constitutes a perfect seal against moisturearoundthe-doOrJ V I V In making up acomplete gasket for; a door, such asshown in Fig. 1, a'single length of this material isusedhaving its endsat. f the point 18. This is mitered out in an opposite direction at eachcorner, leavinga slightamount of sponge rubber-19 and fab ric 12.. Thispermits of bending it around the square corners of the central portion"15 of the door and leaves it in the position". shown'in Fig. 1. V

The material is not only useful for. the doors of ice-boxesand electricrefrigerators,

soft gasket or weather strip is required. 3 f{ Although we haveillustrated, and qde scribed only one form 'ofthe invention, we

are aware of the fact that changes can be 1 made therein by any personskilled in the art without departing from the scope of the invention asexpressed in the claims. i Theree fore we dov not wish to beilimited tothe exact form shown, but what we do claim is v The combination with adoor having a rabbet extending into the edge thereof parallel'with theplane of the door and having a projection extending from'onesurface ofthe rabbet to the edge of the door, of a 2.1.9?

gasket having a semi-cylindrical part provided With a, radial lipextending into the rabbet and a fiat side lying against the projection,the semi-cylindrical surface being adapted to engage the door jamb.

In testimony whereof We have hereunto afiixed our signatures.
